Here is the formula:

The square root of x multiplied by z divided by the square root of y = new injector flow rate

Where:
X = new fuel pressure
Y = original fuel pressure
Z = lbs per hour

First, find the square root of the new and original fuel pressure.
New fuel pressure: square root of 55 = 7.416
Original fuel pressure: square root of 43.5 = 6.595

Then divide the new fuel pressure square root sum by the original.
7.416 / 6.595 = 1.124

Then multiply this total by the size of the injector. In this case we are using the stock Saturn 19lb injectors.
1.124 * 19 = 21.35

At 55psi the injector now flows 21.35lbs/hr
